Since starting the Green Office initiative in the later part of 2007, Greenrock has introduced this project to approximately 40 local companies. We hope that in 2009, we can double this number with the assistance of dedicated volunteers and the support of our Green Office Advisory Panel (GOAP).

Ashley and Chris

A running couple aren't just running for gold anymore. They are running for cash for local charities.

Validus Reinsurance has awarded runners Chris and Ashley Estwanik $5,000 each for the charity of their choice.

Mr. Estwanik, who works for Validus, selected Big Brothers & Big Sisters. Mrs. Estwanik, a teacher at the Bermuda High School for Girls, chose the environmental charity Greenrock ...

One local runner has found a novel way of using her favourite pastime to help preserve Bermuda’s environment. Here, Ashley Couper Estwanik describes her love of running and how she came to support Greenrock while logging miles the pollution-free way.


Corporate CEOs, politicians, transport officials and many others from around the world came together in December to focus on the future of electric vehicles (EVs). Greenrock’s Michael Burke attended the conference in Washington, DC, held by the Electric Drive Transportation Association, and learned more in three days than he had in months of internet research. Here he summarises some of the information and ideas from the symposium.


Solar outdoor lights look like regular outdoor lights, but they are anything but ordinary. 

PV panels collect energy and store it in a deep-cycle, maintenance-free, gel-cell battery. This battery powers the lights at night and can store enough energy to run the lights for five to seven consecutive days without sun.


An independent energy authority is the best way forward for the Island, according to sustainable development group Greenrock.

As the Department of Energy finalises its Green Paper on a National Energy Policy to submit to Cabinet, Greenrock believes an independent authority is the best option.


The Government will build a new hospital for half the estimated price and will do it without building on the Botanical Gardens. That according to the Throne Speech yesterday, though a Bermuda Hospitals Board (BHB) spokesperson refused to reveal further information until a press conference on Wednesday ...

Yesterday a spokesperson for environmental watchdog Greenrock said the group welcomed the Government's announcement but worried about transparency as plans went forward.


In 2007, Greenrock introduced biodegradable picnic ware to Bermuda. Since then, we have been strongly encouraging other local businesses to offer eco-friendly alternatives to conventional products in order to give consumers more sustainable choices.

Now ImportBda is introducing a more eco-friendly, sustainable product choice to the local food services industry. Their aim is to help reduce the amount of waste that will not decompose, waste which is harmful to our environment and whose production contributes to global climate change.


Electric vehicles (EVs) are nothing new. The first electric carriage was invented back in the 1830s, and by the 1900s commercial EVs like platform trucks and the British milk float were common. Fast forward to the present, and EVs are becoming mainstream – all the major car manufacturers are developing new models. 

A conversation at schools about ‘going green’ and why Bermuda’s youth should care

Greenrock’s School Roadshow hit local schools this fall with a strong message about our collective social responsibility – to become more aware about the choices we can make in order for all of us to ensure that we maintain a sustainable state of balance in our community.

The goal of Greenrock is about changing the mindset when it comes to our lifestyle choices. Through this School Roadshow project, we are hoping to show our middle and senior school students that they are the ones who are able to help make meaningful and long-term changes when it comes to Bermuda’s future growth.


With hydrogen such a long way off and pure electric vehicles still having some significant limitations, biofuels are increasingly being seen as an environmentally friendly alternative to fossil fuels that can be introduced now and remain through the short to long term.

Biodiesel is the only alternative fuel to have fully completed the health effects testing requirements of the Clean Air Act. The use of biodiesel in a conventional diesel engine results in substantial reduction of unburned hydrocarbons, carbon monoxide and particulate matter when compared to emissions from petroleum diesel fuel. In addition, the exhaust emissions of sulfur oxides and sulfates (major components of acid rain) from biodiesel are essentially eliminated compared to diesel. (Source:

With the ability of all diesel cars to run on biodiesel mixed at 5 per cent with standard diesel without any modification or warranty problems there is a clear benefit of using biodiesel in low percentage blends.
