Energy Innovation and Environment

Scientific studies indicate significant negative weather, natural disaster probabilities increasing and economic instability in the coming decades. The NEXUS Working Group on Energy Innovation & Environment aims to facilitate NEXUS engagement on these issues and help stabilize the climate and ecological crisis.
History of the Working Group

Anthropogenic greenhouse gases from burning fossil fuels, clearing land, agriculture and industry have exceeded the planet’s capacity to manage solar radiation and maintain the current biosphere. Scientific studies indicate significant negative weather, natural disaster probabilities increasing and economic instability. This will produce additional negative long-term outcomes for biological diversity and vulnerable human populations while we continue to exceed this planetary limit. Current policy and technological trajectories fail to reach scientific expectations for achieving climate stabilization.

The NEXUS Working Group on Energy Innovation & Environment evolved in 2016 from the NEXUS Climate Lab to facilitate NEXUS engagement on these issues and help stabilize the climate and ecological crisis.


The NEXUS Working Group on Energy Innovation & Environment builds bridges to amplify connections, knowledge and engagement on climate solutions.

Actions We’re Taking:

Working Group on Energy Innovation & Environment collaborates on and develops programs for:

  • Climate science and education
  • Existing and proposed government climate policies
  • Climate activism and advocacy
  • Clean energy and technology innovation
  • Creating climate solutions

Our Programming

Climate Science Call Series

Speakers series by call scientists, CEOS, experts and organization leaders in the climate and clean energy space


High-level exclusive delegations and trips to meet with leaders in the climate movement and energy technology investment space. In November, 2021 we are sending a delegation to the UNFCCC’s COP26 in Glasgow, Scotland and are currently strategizing around two areas for impact while we are there.

Collaborative Spirit

Climate change affects poverty, human trafficking, environmental conservation, animal welfare and investing. EIE hosts joint high-level collaborative salons with other Working Groups to learn about how climate change shapes many issues we care about.

Exclusive Salons

Salon dinners with international speakers in intimate settings organized globally around the topics of clean tech, climate policy and other forward thinking solutions to solve the biggest crisis of our time

Public Advocacy

Public advocacy on behalf of important causes and NGOs doing critical work in the field of climate science, promoting innovation and supporting climate solutions
