What are the top ESG Solutions of 2023

Leading green projects around the world.

1. Carbon capture and storage (CCS):


CCS is a technology that captures carbon dioxide (CO2) emissions from industrial processes and stores it underground to prevent it from entering the atmosphere.

It works by capturing CO2 at the source (such as power plants or factories), transporting it to a storage site, and injecting it into deep geological formations like depleted oil and gas fields or saline aquifers.

Case study: 

The Sleipner project in Norway has been injecting captured CO2 into a saline aquifer since 1996, successfully storing over 20 million tons of CO2 to date.

2. Renewable energy development:

Renewable energy development involves the creation, expansion, and utilization of energy sources that are sustainable and do not deplete natural resources.

Renewable energy sources include solar, wind, hydro, geothermal, and biomass.

Case study: 

The Walney Extension Offshore Wind Farm in the United Kingdom, currently the world's largest operational offshore wind farm, generates enough clean energy to power nearly 600,000 homes, reducing CO2 emissions by over 1.2 million tons annually.

3. Green bonds:

Green bonds are debt securities issued by governments, corporations, or financial institutions to raise capital specifically for financing environmentally friendly projects, such as renewable energy, energy efficiency, and clean transportation.

They work by providing investors with a fixed return on investment while supporting projects that contribute to environmental sustainability.

Case study: 

In 2021, Alphabet Inc., the parent company of Google, issued $5.75 billion in green bonds, the largest ever issued by a corporation. The proceeds will be used to fund projects focused on renewable energy, clean transportation, and sustainable buildings.

4. Impact investing:

Impact investing refers to investments made into companies, organizations, or funds with the intention of generating both a financial return and a measurable, positive social or environmental impact.

It works by directing capital towards ventures that align with specific impact goals, such as reducing greenhouse gas emissions, promoting clean energy, or supporting sustainable agriculture.

Case study: 

The Calvert Social Investment Foundation's Community Investment Note has directed more than $1.5 billion into community development projects worldwide, including renewable energy projects, affordable housing, and access to clean water.

5. Sustainable supply chain management:

Sustainable supply chain management involves integrating environmental, social, and economic considerations into a company's procurement, production, and distribution processes.

It works by adopting practices such as sourcing materials from environmentally responsible suppliers, reducing waste and energy consumption, and promoting fair labor practices throughout the supply chain.

Case study: 

Unilever, a global consumer goods company, has implemented a Sustainable Living Plan that aims to source 100% of their agricultural raw materials sustainably by 2030. As of 2020, the company has achieved 62% sustainably sourced agricultural raw materials, reducing their overall environmental footprint and promoting sustainable farming practices.

6. Circular economy practices

A circular economy is a model that aims to eliminate waste and promote the continual use of resources through recycling, remanufacturing, and repurposing.

How it works:

  •  Designing products for longevity and easy disassembly
  •  Encouraging sharing and leasing models
  •  Recovering and recycling materials from discarded products

Case study: 

Philips has adopted circular economy practices, offering products as a service (e.g., selling lighting as a service rather than individual light bulbs) and implementing take-back schemes for their products.

7. Environmental, Social, and Governance (ESG) reporting

ESG reporting refers to the disclosure of a company's environmental, social, and governance performance to stakeholders.

How it works:

  • Companies assess and report their environmental impact, social responsibility, and governance practices
  • Investors use this information to make informed decisions about the sustainability of their investments

Case study: 

Unilever publishes an annual ESG report, detailing its progress on sustainability goals, such as reducing greenhouse gas emissions and promoting ethical sourcing.

8. Energy efficiency measures

Energy efficiency measures involve reducing the amount of energy required to provide products and services.

How it works:

  • Implementing energy-saving technologies and practices
  • Encouraging behavioral changes to reduce energy consumption

Case study: 

Walmart has implemented various energy efficiency measures, including installing LED lighting in stores and investing in renewable energy projects, resulting in a 20% reduction in energy usage per square foot since 2010.

9. Sustainable Investing

Sustainable investing considers environmental, social, and governance factors when making investment decisions.

How it works:

  • Investors assess companies' ESG performance before making investment decisions
  • Divesting from companies with poor ESG performance and investing in those with strong ESG performance

Case study: 

BlackRock, the world's largest asset manager, has integrated ESG factors into its investment strategies and committed to aligning its portfolio with the Paris Agreement goals.

10. Corporate social responsibility (CSR) initiatives

CSR initiatives are voluntary actions taken by companies to improve their environmental, social, and governance practices.

How it works:

  • Companies develop and implement programs to reduce their environmental impact, engage with local communities, and promote ethical business practices
  • Communicating CSR initiatives to stakeholders to demonstrate the company's commitment to sustainability

Case study: 

Patagonia is known for its strong CSR initiatives, including donating 1% of sales to environmental causes, using recycled materials in its products, and advocating for environmental policy changes.

11. Biodiversity conservation

Preserving and protecting ecosystems, habitats, and species to maintain the diversity of life on Earth

How it works: 

By implementing policies, strategies, and management plans to conserve and restore natural habitats and ecosystems, and protect endangered species


Case study: 

The Great Barrier Reef Marine Park in Australia, which is a protected area that aims to conserve the biodiversity of the reef ecosystem while supporting sustainable use and development

12. Water management and conservation

 Efficient and sustainable use of water resources, minimizing water waste, and protecting water quality

Through water-saving technologies, infrastructure improvements, demand management, and water quality monitoring and regulation

Case study: 

The City of Las Vegas has implemented several water conservation measures, including a water-smart landscaping program, water-saving plumbing fixtures, and strict watering restrictions, which have led to a 28% reduction in per capita water use since 2002

13. Emissions trading schemes

Market-based approach to reducing greenhouse gas emissions by setting a cap on emissions and allowing companies to trade allowances

Companies that emit less than their allocated allowances can sell their excess allowances to companies that exceed their cap, creating financial incentives for reducing emissions

Case study: 

The European Union Emissions Trading System (EU ETS), which covers more than 11,000 power stations and industrial plants in 31 countries, has contributed to a 29% reduction in emissions from regulated sectors between 2005 and 2019

14. Climate risk assessment and adaptation

Evaluating the potential impacts of climate change on natural and human systems and developing strategies to reduce vulnerability and increase resilience

Using climate models, risk assessments, and stakeholder engagement to identify and prioritize climate risks and develop adaptive measures

Case study:

The Netherlands' Delta Programme, which assesses the country's flood risks, freshwater availability, and spatial planning to ensure long-term protection from climate change impacts such as sea-level rise and extreme weather events

15. Green building and smart city development

Green building:

Green building refers to the design, construction, and operation of buildings with a focus on energy efficiency, resource conservation, and occupant health and well-being.

Green buildings incorporate sustainable materials, energy-efficient systems, and water-saving technologies, aiming to reduce the overall environmental impact.

LEED (Leadership in Energy and Environmental Design) is a globally recognized certification system for green buildings.

Case Study: 

The Salesforce Tower is a LEED Platinum-certified building completed in 2018.

The building uses an innovative underfloor air distribution system, which reduces energy consumption by 30% compared to traditional HVAC systems.
