The world's seven billion people consume varying amounts of the planet's resources. The same goes for the type of meat or fish you eat or the type of jeans you buy. If we take the example of transport, taking the plane emits 285g of carbon per kilometre, compared to 104g for a car and 14g for a train. How much carbon is emitted to produce your t-shirt, meal or phone? The amount will depend on production and consumption choices. Carbon footprint is a concept used to quantify the impact of an activity, a person or a country on climate change. Greenhouse gases are emitted through the production and consumption of goods and services. As an individual, you can also estimate your carbon footprint and reduce it. Many countries, institutions and companies have committed to reduce their emissions while the EU has even set the objective of being “climate neutral” by 2050. When you drive your car, buy a pair of sneakers or grill a steak, you contribute to the emission of carbon dioxide and other greenhouse gases into the atmosphere. The discrepancy of about 30 centimetres might appear small, but every bit of vacant defensive space has a bearing on the momentum of each set of six tackles.Eating, travelling, heating your home… What's the carbon footprint of these activities and how can we make more climate-friendly choices? In the NRL, winning teams average 6.7 pre-contact metres compared to 6.4 for the losers. It interconnects in so many different ways.” When you think about the run you make off a quick play-the-ball, you are likely to get more pre-contact metres. “That for me spilled into the idea of quick play-the-balls, which are so important. I don’t know where he ranks, but he gets the ball flat, at speed and chews up as many metres as possible before the defence gets to him. It’s bang, take the ball and as much ground as you can. And that is fullbacks who don’t just jog back into the line, they’re doing everything they can to take the metres on offer, not scanning and moving across the field. “Anecdotally, the moment the next big thing is pre-contact metres, I can see the picture of what is being talked about. ![]() There’s always a lot of people in the picture wherever the ball is. “The other thing I believe about Penrith is they take this almost AFL-type approach to defence they flood zones. In Origin II, the Maroons again came out on top with 6.01, compared to 5.94. It’s a consistent video and training thing for most of the top teams, usually in defence.”Īccording to figures adapted from the official NRL statistics, the Maroons made 6.57 pre-contact metres per run, compared to NSW’s 6.11, in the first game this year. “We talk about it in terms of line speed and restricting the metres pre-contact. “Whether it’s pre-contact metres or line speed metres or defensive metres per carry, it’s a pretty big stat in the game and has been for us for a while,” says the coach, who did not want to be named because he was concerned about giving rivals inside knowledge on his club. Ramy Haidar, an NRL analyst and consultant to several clubs, believes it is the biggest determinant of match results, while a leading coach described the metric as “one of the first stats we go to after each game”. The importance of limiting the opposition’s pre-contact metres, via good defensive line speed, is a key focus for many in the game. ![]()
