Key Trends for Sustainability | Tunley Environmental

Sustainability will remain a subject of great interest on a global scale as the world strives to establish a more sustainable civilisation. The year ahead will bring several key developments that will shape the trends for sustainability in 2025 in various sectors.  

Expansion of Regulations and Compliance Requirements 

In the coming year, businesses will face robust and streamlined regulations designed to improve transparency and sustainability compliance. The focus will be on simplifying existing laws and creating a unified framework for reporting, making it easier for businesses to comply with sustainability standards. 

• The UK’s Financial Conduct Authority (FCA) has extended its enforcement of anti-greenwashing rules to April 2025. 

• The European Union (EU) has already indicated that it will introduce a consolidated framework for sustainability reporting, integrating existing regulations like the Corporate Sustainability Reporting Directive (CSRD) and the EU Taxonomy Regulation. 

• EU authorities have also announced a review of its Carbon Border Adjustment Mechanism (CBAM) by the end of 2025 to expand the scope of covered goods.

These sustainability and reporting trends in 2025 will lead to a more unified, transparent and accountable regulatory environment, designed to improve the overall effectiveness of sustainability efforts. 

Increase in Clean Energy Integration 

The global transition to clean energy is expected to accelerate in 2025. Technological advancements and policy shifts will drive the adoption of renewable energy and efficiency solutions. 

• Research from the International Energy Agency (IEA) indicates that renewable energy sources are projected to account for 35% of global electricity production, with wind, solar and hydroelectric power leading the way. 

• Electric vehicle (EV) sales are expected to double by 2025, fuelled by advancements in battery technology and expanding charging infrastructure. 

• Countries such as Japan and Germany are pushing forward with hydrogen projects, which will play a key role in decarbonising heavy industries by 2025.

Sustainability Solutions will be Community-Led 

With the growing need to adapt to climate change, community-led and nature-based solutions will take centre stage in 2025. These approaches will be critical for addressing biodiversity loss, building resilient communities and enhancing climate adaptation efforts. 

• Reforestation, wetland restoration and other nature-based solutions will become increasingly vital for addressing climate change and biodiversity loss, especially in vulnerable regions. 

• Cities will invest in sustainable urban planning, focusing on energy-efficient buildings, green spaces and public transportation systems. 

• Local communities, especially in Small Island Developing States (SIDS), will lead efforts in sustainability, leveraging international collaborations to address their unique vulnerabilities. 

These trends on sustainability highlight the importance of local, nature-based solutions to build resilient ecosystems in the face of a rapidly changing climate.
