Parliament calls for greater sustainability in transport infrastructure

Parliament’s Environmental Audit Committee has published a report calling for greater sustainability from the Department for Transport in future infrastructure projects.

According to the report (which can be read here), The Department for Transport needs a clear strategy to increase the use of ultra-low emission vehicles, reduce air pollution and deal with the VW cheat device scandal so that it can meet decarbonisation and air quality targets.

The Environmental Audit Committee highlights that the Department for Transport has planning and investment responsibilities for the UK’s road, rail, maritime, aviation and bus service sectors. The Department’s total spending is set to increase during this Parliament: although its resource spending is due to go down, its capital budgets will rise, with £73.4 billion of transport-related capital investment between 2015–16 and 2020–21, including £34.5 billion for Network Rail and £15.2 billion for its Roads Investment Strategy. In 2014–15 the Department allocated 50% of its gross expenditure to its roads, traffic and local responsibilities; almost 40% to its rail executive responsibilities; and 3% to its international, security and environment responsibilities.

Whilst Parliament acknowledge that many positive steps have been made towards better sustainability within the transport sector, the report focuses on those areas where the Department for Transport might go further to tackle climate change.

This has been welcomed by Campaign for Better Transport who will be writing to the Department demanding further reduction of their carbon footprint.

Sustainable Transport Campaigner, Bridget Fox commented: “The report shows that the Government is not doing enough to decarbonise transport and avoid building damaging infrastructure projects. Stronger action to clean up polluting vehicles is welcome but ultimately the answer lies in reducing car dependency, getting more freight onto rail and investing in good quality public transport alternatives. The call today from Team GB’s Olympic cycling champions for investment in everyday cycling is part of this solution. We’ll be writing to the Department for Transport Permanent Secretary demanding action on this report.”

Costa Rica running on renewables for 121 days and counting!

Costa Rica is setting the precedent for other nations looking to utilise green energy and reduce their carbon footprint.

The small Central American nation has generated 100% of its electricity from renewable sources for the past 121 days, and the run isn’t over yet. The country, which draws clean energy from a variety of renewable sources, still has its sights on a full year without fossil fuels.

With a 121-day stretch of 100% renewable energy under its belt and several months left in the year, Costa Rica appears to be edging closer to its admirable target. Costa Rica could be on track to match the record set with its renewable energy production last year, which accounted for 99% of the country’s electricity. That included 285 days powered completely by renewable sources, according to the Costa Rican Electricity Institute.

Costa Rica is able to take advantage of a multitude of renewable energy sources because of its unique climate and terrain. Most of the nation’s renewable energy comes from hydropower, due to its large river system and heavy tropical rainfalls. Solar, wind, biomass, and geothermal energy also play key roles.

Green ambitions

Costa Rica have shown great ambition in the field of renewable energy over the past few years and according to the government they are aiming to be entirely free from fossil fuels by 2021. However, with large sums of money currently being invested in geothermal energy projects, it is anticipated that this impressive target could indeed be met much sooner than originally expected.

In comparison, some countries (ourselves included) could be perceived as simply not doing enough to tackle climate change and improve our energy habits. Costa Rica achieving 99% renewable energy usage this year sends a stark message to the rest of the world of what is possible when a country unites to make a concerted effort to fight global warming using sustainable energy sources and technologies already at our disposal.

CO2: Don’t be neutral, be negative!

It is common knowledge that in order to effectively combat global warming caused by CO2, we need to make conscious efforts to reduce our carbon footprint. Given that buildings are accountable for 37% of total UK greenhouse gas emissions (according to the Committee on Climate Change) we have a duty as specifiers, architects and construction professionals to lower this alarming figure. Joe Bradbury of www.buildingspecifier.com investigates.

Going neutral isn’t enough

Whenever CO2 reduction is discussed, we often talk about becoming carbon neutral, i.e. designing or retrofitting our building to use only as much atmospheric CO2 as it emits, leaving existing levels intact. However, approximately 30 billion metric tons of carbon dioxide is pumped into the Earth’s atmosphere from power plants, vehicles and various other industrial sources which are intensively fuelled from the burning fossil fuels. So, whilst going neutral can certainly help the problem, it’s a mere drop in the ocean in terms of fighting climate change.

We therefore need to not only focus on reducing how much CO2 we produce, but also on how we can physically remove it from the air.

Capturing CO2

Allison Dring, head of start-up Elegant Embellishments, has designed a smog-eating façade that is a perfect example of how a building can go a step further and actually become carbon negative. Described on the BBC, “The façade is coated with a special paint made from titanium dioxide, a pollution-fighting technology that is activated by daylight. It absorbs the fumes generated from traffic and converts them first into nitric acid and then into calcium nitrate, which is harmless.”

The facade has currently been fitted on the side of a hospital in Mexico City, where pollution is a massive issue. Since being added to the building, the innovative façade has allegedly reduced pollution of around 1,000 cars per day, perhaps resulting in less people needing to visit the hospital in the first place!

Allison is a staunch advocate of the idea that the materials we build with should actively give something back to the environment – and so am I.

Putting it to good use

Becoming carbon negative is a two stage process; consuming the CO2 is only the first part of the solution. What do you do with the CO2 once it has been captured from the air? Turning it into usable materials or less harmful gasses is the key to becoming truly carbon negative and actually being an asset to the environment.

Atmospheric CO2 is one of the biggest issues of the 21st century… however, as the old adage “one man’s waste is another man’s treasure” implies, it is also a precious resource! We can use the CO2 taken from the air and convert it into useful carbon-based products, such as building materials, pharmaceuticals, fuels and plastics.

Not only do these products help us as an industry, but the very creation of them absorbs more CO2 than we emit, ergo reducing CO2 in the atmosphere. Now THAT is a solution.
So in short, when it comes to tackling climate change in the built environment, be negative!
